Bratton is moving to New York next month for a cushy job in the private sector, acting as CEO of Altegrity Security Consulting. But last week he had an interesting response when asked by theNew York Daily News if would consider returning to the NYPD some day.

"Oh sure. I'm only 61. That's a possibility down the line," Bratton told the News. "Those that know me know I never close any doors. Well with some exceptions: I've closed the door on politics to show my sanity. I'm not crazy."

Could history repeat himself and Bratton one day replace Kelly just as he did in 1994, when Mayor Giuliani fired Kelly?

"Maybe we can have a revolving door, as he exits I come through and vice versa," Bratton joked to the News. "We can have our own long-running Broadway play, alternating the lead actors."
